In 2026, purchasing LLM tokens has diversified into four main categories, each with distinct pricing and features. Native APIs from model creators like OpenAI and Anthropic offer day-one access to new models and exclusive features, though managing multiple keys and billing can be complex. Open-weight inference hosts, such as Together, provide significantly cheaper tokens by leveraging public model weights, with prices as low as $0.05/M tokens for models like GPT OSS 20B. API routers consolidate access to multiple vendors under a single key, often at list price plus a small fee, while cloud platforms like Google Cloud Vertex AI offer procurement services with tiered pricing structures that can increase costs.
